1. Summary
The nextbike on-boardcomputer is integrated into the nextbike smart bike. This on-
boardcomputer enables the customers to rent and return smart bikes directly through its
interface via Smart Card and mobile number including PIN code, automating the release
and lock process for all registered customers. Customers without Smart Cards or
personal log in information also have the choice to activate the rental via App or phone
call to the IVR-service hotline.
Furthermore, the system is connected to the nextbike Office Software via existing
GSM/GPRS network and GPS satellites, which permits locating and monitoring bicycle
in real time on kiosk terminals, App or calling the IVR-service hotline.
2. Applications
o Bicycle rental/return
o Bicycle tracking
3. Hardware Description
3.1 Nextbike’s components:
On the bike a boardcomputer (above the rear wheel) and a lock unit (at the front) is
mounted, which are connected by a 2-pin cable. The lock unit contains a motor for
locking a bar and two switches for detecting an inserted bar and the motor end position.
Apart from that, the boardcomputer is connected to the generator parallel to the two
lamps of the bicycle.
The lock unit FVML is encapsulated in a plastic housing board. The built-in components
and connections are clearly in Figure 2.
The boardcomputer FVM2 consists of two PCBs (base PCB and antenna PCB) that are
connected by an 8 pin ribbon cable and inserted into a housing. The structure is shown
in Figure 1. On the bottom side of the housing a 4-pin connector is screwed, which is
soldered to the base PCB. So the generator and the lock unit can be connected.
Besides boardcomputer includes the following main components:
o A 10-number keyboard to wake up the system and to enter information (codes, ID
o numbers and pins)
o A RFID-Reader to wake up the system and to read customer cards
o A display and LEDs to show status, lock codes and other information
o A speaker for key feedback and alert tones
o A GSM module for communication with central server
o A WPAN-module (Synapse SM200) for local data exchange with the terminal
4
o A boost converter and a high side switch for supplying the lock unit
o A power supply unit including battery
o A Microcontroller with serial data flash memory
o The system is supplied by an on-board battery that is charged by the bicycle
generator.
Cautions:
A. Are developed with particular focus on vandalism and weather resistance
(temperature range between 14 °F and 122 °F).
B. Are developed for energy efficiency. As a standard the boardcomputer rests in
sleep modus. With activating the unit via numeric key-pad the unit wakes up for 8
seconds if no other activity is recognized. The boardcomputer is designed to
operate without any recharging for several weeks. One ride per week of 15-30
minutes will be sufficient to recharge the battery to 100%.
C. The units are fixed in the upper cover of the back wheel.
D. The electric components are covered by a waterproof glued acrylic box.
E. Please maintain a minimum distance of 20 cm from the antenna.

4. Functional Description
4.1 Powermanagement
The boardcomputer mostly lingers in the sleep mode to reduce power consumption. The
LED display is completely off during this time and the status LEDs indicate status
cyclically by flashing.
Waking up the system can happen from following wake up sources:
o Push a button
o Apply a RFID-Card
o Ride the bike
o Connect a fast charger
o Timer interrupt for central server via GSM-Call the boardcomputer from terminal via
WPAN
In operating mode control and display elements, acoustic feedback and communication
are active.
Depending on the Battery charge level the boardcomputer switch to a power saving
mode. In this case, the system status is not indicated by the flashing LEDs. In addition,
the device cannot wake up.
Charging the batteries during riding the bicycle is controlled by the µC. The charge
current depends on the speed of the bicycle, the Battery charge level and the ambient
light.
By connecting a fast charger (5V maximum voltage, current maximum 4A), the battery
can be charged completely within about 20 minutes. During that the current charge
status [%] is displayed
.
4.2 Control and display
In idle mode red or green LED blinking indicates, if the bike is available for a rental or
not. Pushing a button or placing a customer card wakes up the system.
After pushing a button, the customer is prompted to enter either the current lock code or
phone number and pin.
Entering the lock code directly leads to an opening of the lock. This happens if the
customer has just temporarily parked the bike or the rent it another way (eg. mobile
phone).
By entering the phone number and pin, a client can authenticate similar to placing a
customer card. This leads either to a query via WPAN, in internal memory or via GSM.
Thus, the lock is only opened after appropriate approval by the central server or the
successful check in the internal memory.
9
If the user authenticates himself as a service employee, an appropriate message is
displayed and a connection between boardcomputer and central server is established
for exchanging data. For example, a new lock code can be transmitted.
After every key press a short acoustic feedback sounds, after each RFID authentication
a long one.
After 1st key operation a message is displayed in the default language. Thereafter, a
user specific language can be used.
4.3 Communication via GSM
4.3.1. Frequency band and access to the medium
The communication between boardcomputer and central server is running via GSM-
band.
The boardcomputer initiates a TCP connection to the central server, which is afterwards
used for shipping messages in both directions.
4.3.2. Communication sequence
Prior to establishing the communication the modem needs to be initialized. This is done
via AT commands. After initiation of communication by the boardcomputer, the server is
always the master. It sends requests, commands and data to the boardcomputer. The
communication is terminated by the server or a timeout.
4.4. Communication via WPAN
Unlike the communication via GSM local communication can also be initiated from the
terminal. For this, the boardcomputer listens every 3 seconds on the bus. Accordingly,
the terminal must send a burst for more than 3 seconds.
After establishing the connection, the two communication paths are identical.
4.4.1. Encryption
The data transfer is encrypted by AES128.
4.5. Position recognition via GPS
After switching on the GSM modem, GPS position is queried. The transfer of the
determined coordinates is initiated by the central server.
4.6. Data memory
In the data memory of the boardcomputer customer data are stored. So after
authentication in a very short time can be determined, whether the user is
allowed to borrow the bike. Additionally an individual user language can be stored.
10
If the user cannot be found in the internal database, a request is sent to the central
server. With a positive response, the bike can be released.
If data memory shall not be used, it just stays empty. Thus all data is automatically
requested at the central server.
